Cleaning up the pie
The pie chart you made in the last plot is good, but it's a little cluttered. Let's clean it up using the ggplot function theme_void() along with giving it a meaningful title with ggtitle(...).
The disease_counts summarized data frame from the last exercise is already loaded for you.
This exercise is part of the course

Hands-on interactive exercise
Have a go at this exercise by completing this sample code.
ggplot(disease_counts, aes(x = 1, y = total_cases, fill = disease)) +
# Use a column geometry.
geom_col() +
# Change coordinate system to polar.
coord_polar(theta = "y") +
# Clean up the background with theme_void and give it a proper title with ggtitle.
